International Justice Mission is not a new name. They've been accused of progressive groups previously of exaggerating rates of sex trafficking and of being anti sex work.
In a submission over chat control, they submitted a rather sleazy and manipulative proposal where they pointed to "terminology guidelines". These guidelines are far less guidelines than they are puritanical propaganda of how they want terms to be interpreted.
Usually, this is in a very harmful manner. A victim / survivor writing about their abuse? Well, you have just produced "child porn" and we've got to investigate you. IJM doesn't really care about the harms of what they do though. These kinds of groups never do.
